OK, I prepared to accept that I'm doing this wrong but...

I have a grid that includes the following column definition ...
<telerik:GridBoundColumn  
  HeaderText="Name"  
  SortExpression="Name"  
  UniqueName="Name"
</telerik:GridBoundColumn> 

My code behind reads something like this ...

var l = from contact in contacts 
        select new 
        { 
           ContactID = contact.ContactID, 
           Name = contact.LastName + ", " + contact.FirstName, 
        }; 
gdContacts.MasterTableView.DataSource = l; 

When I run this, rather than a value of "Hemming, Stuart" the "Name" column contains a ".ToString()"-like value that reads "{ContactID=1, Name="Hemming, Stuart"}.

Things work as expected if I change my column definition to a template column like this...
<telerik:GridTemplateColumn 
  HeaderText="Name" 
  SortExpression="Name"  
  UniqueName="Name"
  <ItemTemplate> 
    <asp:Label runat="server" ID="lblName" Text='<%# DataBinder.Eval(Container, "DataItem.Name") %>' /> 
  </ItemTemplate>                     
</telerik:GridTemplateColumn> 

So, why is that?

Enquiring minds, and all that.

Stuart,

You are missing the DataField property from the GridBoundColumn declaration.

All the best,

[FX: Peers at code. Does a double-take and slaps head] Doh!

And you have no idea how long I looked at that code.

Sometimes, I shouldn't even be allowed out!

Thanks Rosen.
